90 mallet: coal-fields of the naga hills. 



(7.) On the Revenue Survey map several 'pungs^ are marked along 

 the western side of the Tipam range near Chapatoli. Some of these are 

 probably petroleum springs. 



(8.) Close to the Hukanjuri path, about two miles from Jaipur, 

 petroleum exudes from the bank of a nalla, 50 yards below the 9-feet 

 seam (p. 50). Captain Hannay mentions other springs also in this 

 neighbourhood. The locality called Nahor Pung, where borings were 

 made unsuccessfully in 1866 (p. 11), is about a quarter of a mile distant. 

 Half a mile or more to the eastward there is a spot where petroleum 

 exudes from Sub-Himalayan sandstone. 



(9.) There are at least two springs in a nalla half a mile north of 

 the Disang. 



(10.) Captain Jenkins mentions several small springs about a quarter 

 of a mile from the Disang (p. 7). 



(11.) On the bank of the Teok, near the faulted junction between the 

 Sub-Himalayan sandstones and the Disang group, there is a spot where 

 the former are impregnated with petroleum. The coal measures are in 

 all probability below the surface here. > 



(12.) Mr. Bruce mentions oil-springs in the bank of the SafFrai, and 

 in another locality not far from his coal quarry (p. 4). 



(13.) Some 3 or 4 miles to the south of Tirugaon, petroleum exudes 

 in small quantity from the Sub-Himalayan sandstones. 



(14.) At the head of the Tiru I observed petroleum oozing from the 

 coal-rocks in four or five places. Where it is most plentiful, it issues from 

 a rather massive sandstone dipping west 40° north at 80°. There is 

 another spring in the same band of rock, about 100 yards distant. 



(15.) At Tel Pung, on the Dikhu, a band of fine-grained, massively- 

 bedded sandstone, similar to that in the Tiru, strikes across the river, 

 dipping west-15°-south at 80°. These beds are inverted, being overlaid 

 stratigraphically by thin-bedded sandstone, dipping east-10°-south at
